IMPROVED CAP FOR OIL-CANS.

Specification forming part of' Letters Patent No. 31,866, dated April 2,1861. n

To @ZZ whom it may concern.-

Beit known that I, J. H. BRECKENRIDGE, ot' the town of Meriden, in thecounty of New Haven and State of Connecticut, haveinvented a new andImproved Cap for Cans, Sto.; andi I do hereby declare that thefollowingis a full, clear, and exact description thereof, referencebeing had to the annexed drawing, making a part of this specification,and to the lettersof reference marked thereon.

This cap pertains to that class which are secured to the can by means oflugs or projections upon the neck of the can. The common method iseither to have the cap made of such a thickness that suitable cam-shapedor bayonet-formed recesses may becut upon the interior ofthe. cap to fitthe lugs, or if the cap is made thin ofsheet metal, then the sides arecut through into the bayonet shape. The first method is objectionable,because the whole cap `must be made thick, heavy, and clumsy, While theformation of the grooves is difficult, consumes much time, and isexpensive. The second method is also objectionable, on account ot' thecost and difficulty of properly cutting out the metal, and also becauseit renders the cap weak in consequence ot' having its sides or banddivided. Y

My invention consists of an improved article of man ufacture-viz. asheet-m etal cau-cap having a portion of its exteriorsurface raised intothe form of a hollow groove or groovesto receive the lugs, as will behereinafter shown and described. y p

In the drawing, Ashows one of my improved caps in perspective andpartially upturned, 2 indicating the raised groove for receiving thelugs.

`D shows the' neck of the can, lindicating the 1ugs,which tit into thegrooves 2.

F is a side elevation of my improved cap, having a portion of itssurface raised, so as to form the hollow groove 2, as shown. Whendesired, a spring, B, may be placed within the head ofthe cap, as shownat E. A disk of cork, C,is then placed upon the spring withinthe cap.Vhen a cap thus provided is placed upon the can, the edge thereof comesin Contact with the cork, and a. tight joint is formed. Any otherelastic material may be substituted for the. I

spring and cork. i

My improved cap is made wholly of sheet metal by means of dies of properform. j These caps are produced with great rapidity and very cheaply.The sheets or blanks are fed between the dies, which then move and at asingle blow form the cap complete. All filing, cutting, andiitting arethus saved, no stock is wasted, and the time of Workmen is greatlyeconomized. i

My improved cap is much stronger than the open-grooved or cut caps,because in my improvement the band of the cap remains entire. lFor thesame reason -it is also much more convenient in placing upon or removingfrom the can. There are no sharp corners to abrade the ngers. Y j lHaving thus described my invention, I claim and desire to secure byLetters lPatent as an improved article of manufacture- A sheetmetalcan-cap havinga portion ot" its exterior surface. raised and formed intoa groove of the form herein shown and described, for the purposessetforth.
